TRANSPORTABLE CONTAINER FOR ACIDS OR OTHER LIQUIDS Filed June 5, 1953 .INVENTDR synuey c. NIELSEN TRANSPORTABLE CONTAINER FGR ACm OR OTHER LlQUlDS Sydney (Iain Nielsen, Melbourne, Victoria, Australia Application June 5, 1953, Serial No. 359,835

Claims priority, application Australia June 11, 1952 7 Claims. (Cl. 222-176) This invention relates to an improved readily transportable container, intended particularly for acids, alkalies or the like, but usable also for oils, kerosene, solvents or other liquids.

Corrosive acids and like dangerous liquids are usually transported in earthenware or glass carboys enclosed within stout rectangular wooden casings or frames. These containers have many disadvantages in use. They are costly to produce and found very awkward to hand and stow. Again, they are inconvenient to pour from and the wooden casings deteriorate rapidly, chiefly because of the effects of spilled acid.

The object of the present invention is to provide an improved type of container which overcomes these disadvantages.

According to the invention, the improved container comprises a body member which holds the liquid and has a pouring orifice and discs or rings on said body member for convenient transport of the container by rolling and also for tilting of the body member for pouring of the liquid from the pouring orifice, the whole being so constructed that the centre of gravity causes the container to roll on the discs or rings and automatically assume a stable position in which the pouring orifice is uppermost.

The body member is eccentrically arranged in relation to the discs or rings so that the centre of gravity of the container is out of register with the mathematical centre of the rings and, in the stable position of the container, the centre of gravity lies below the mathematical centre.

The invention is more fully described and ascertained aided by reference to the accompanying drawings wherein:

Fig. 1 is a longitudinal sectional view of the improved container in the preferred constructional form.

Fig. 2 is a cross-section taken substantially on the line 22 of Fig. 1.

Fig. 3 is a detail view of a convenient form of pourer for use with the container.

As is shown in these views, the container comprises the cylindrical body member 1 and two end discs 2. Each end disc comprises two circular pressed metal plates 3 and 4 rivetted or otherwise rigidly secured together. The marginal portions of the plates 3 and 4 have shaped parts 5' which, when the plates are secured together, coact to form hollow rims or tyres 6 on the end discs.

The inner plates 4 are shaped to provide inwardly extending circular projections 7 and the body member 1, in addition to having end walls 8, has a marginal flange 9 at each end projecting beyond the end wall 8 to fit over the circular projection 7. The end discs 2 and the body member 1, when so assembled, are secured together by means of longitudinal tie rods it) which are preferably screwthreaded at their ends to receive tightening nuts 11.

The inwardly extending circular projections 7 are eccentrically arranged in relation to the centres of the end discs 2 so that the body member 1 when clamped in position between the end discs is similarly eccentrically disposed with regard to the end discs. By this means the 2,813,663 Patented Nov. 19, 1957 centre of gravity of the container as a whole is out of register with the mathematical centre of the end discs. This is shown in Fig. 2 where the numeral 12 represents the mathematical centre and 13 the centre of gravity of the container.

The body member 1 may itself form the liquid container, in which case it is constructed to be liquid tight. Preferably, however, the body member encloses or houses an earthenware, glass or other vessel 14 which forms the container for the liquid. The vessel 14, or the body member if the latter forms the liquid container, has a pouring orifice 15 closed by a hung 16. The pouring orifice is disposed diametrically opposite the centre of gravity 13 as shown in Fig. 2.

The improved container has many advantages. It can be readily transported by rolling on its end discs 2 and thus does not have to be carried or lifted bodily as is necessary with existing acid carboys. It can also be readily stowed and, if desired, stacked endwise upon its end discs.

Pouring of the acid or liquid contents from the orifice 15' is greatly facilitated as the container can be tilted simply by rolling it on its end discs 2. By reason of the eccentric arrangement of the body member in relation to the end discs 2, the tilting action raises the centre of gravity so that the container will, upon release, roll back on the end discs and automatically assume the stable position as shown in Fig. 2 in which the centre of gravity 13 is directly beneath the mathematical centre 12. In this position, the pouring orifice 15 is uppermost and leaking or dripping of the liquid from the pouring orifice is avoided.

The improved container as a whole can also be produced at lower cost than the existing encased type of acid carboy and it also has other advantages in regard to filling.

To facilitate pouring of the liquid from the container, a detachable pourer 17 may be provided to screw into or otherwise fit the pouring orifice 15, see Fig. 3. Said pourer may have an angularly set spout 13 which pro duces a quick cut-off action after pouring and, by assuming an upwardly inclined position when the container returns to the stable position, avoids dripping of the acid or liquid from the spout as the liquid tends to flow back into the spout instead of dripping therefrom.

To strengthen the end discs 2 the outer circular plates 3 may have circular reinforcing ribs 19. The inner plates 4 may also have eyes 20 through which a rod, wire, rope or other member may be passed to anchor a number of the containers against rolling movement, as for instance when they are stowed on board a ship or in a railway truck. The eyes can also be used when the containers are being lifted or loaded by means of a sling, cargo hook or the like.

What I claim is:

l. A transportable container for liquids comprising a hollow body member which holds the liquid and has a pouring orifice at one side and circular elements on said body member for convenient transport of the container by rolling and also for tilting of the body member to lower the orifice for pouring of the liquid from the pouring orifices, the body member being eccentrically ar ranged in relation to the centre of the circular elements so that the centre of gravity of the container is out of register with the mathematical centre of said elements causing the container to roll on the elements and automatically assume a stable position with the centre of gravity below the mathematical centre of the elements and the pouring orifice at the uppermost side of said body member.

2. A transportable container for liquids comprising a generally cylindrical body member which holds the liquid and has a pouring orifice and circular discs on said. body member for convenient transport of the container by rolling and also for tilting of the body member for pouring of the liquid from the pouring orifice, the body member being eccentrically arranged in relation to the centre of the discs so that the centre of gravity of the container is out of register with the mathematical centre causing the container to roll on the discs and automatically assume a stable position with the centre of gravity below the mathematical centre of the discs and the pouring orifice uppermost, said discs each consisting of two circular pressed metal plates secured together.

3. A transportable container for liquids as claimed in claim 2 wherein the pressed metal plates have shaped marginal portions which, when the plates are secured together, co-act to form hollow rims on the discs.

4. A transportable container for liquids as claimed in claim 3 wherein the discs-each have an inwardly extending circular projection and the body member has a marginal flange at each end to fit over the circular projection.

5. A transportable container for liquids as claimed in claim 2 wherein the outer plate has reinforcing ribs.

6. A transportable container for liquids as claimed in claim 2 wherein the inner plate has an eye.

7. A transportable container for liquids as claimed in claim 1 including a detachable pourer to lit the pouring orifice, said pourer having an angularly set spout.
